Summary: Two successive operators are considered incorrect syntax

Initial Comment:
RKward considers a few syntactic peculiarities as incorrect (and highlights them in red), while they work perfectly well if run in R. They are not always advisable, but that's another question. The common factor to all these cases is apparently that two arithmetic operators are juxtaposed.

1) Repetition of the multiplication sign
** like in 2**2

2) Juxtaposition of + or - and another operator
<-- like in: a<--2
/- like in: a/-2
*- like in: a*-2
**- like in: a**-2
^- like in: a^-2
-- like in: a--2
-+ like in: a+-2
(same with +)
